AC-Coupled module inputs

[List, Christopher]

Hi folks - 

I was pondering something last night about module design philosophy. Why
would you put ac-coupling caps on module inputs, or have them be switchable?
Wouldn't it make more sense to have all inputs uncoupled, and just make sure
that any module that is supposed to produce or process audio ac signals
doesn't have a dc offset on it's output?

...and for external sounds have a separate ac-coupled input mixer /
amplifier...

- Comments?
